Anigozanthos plant named ‘Rambubona’

ABSTRACT

A new and distinct cultivar of  Anigozanthos  plant named ‘Rambubona’, characterized by its compact and upright plant habit; freely and early flowering habit; freely branched flowering stems; and large bright yellow-colored flowers.

Botanical designation: Anigozanthos flavidus.

Cultivar denomination: ‘Rambubona’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anigozanthos, botanically known as Anigozanthos flavidus, commonly referred to as Kangaroo-Paw, and hereinafter referred to by the name ‘Rambubona’.

The new Anigozanthos is a product of a planned breeding program conducted by the Inventor in Tuggerah, New South Wales, Australia. The objective of the breeding program is to create new compact Anigozanthos cultivars that are suitable for container production, are freely flowering and have bright flower coloration.

The new Anigozanthos originated from a cross-pollination made by the Inventor on Oct. 10, 1998 in Tuggerah, New South Wales, Australia of a proprietary selection of Anigozanthos flavidus identified as code number 190/1, not patented, as the female, or seed, parent with a proprietary selection of Anigozanthos flavidus identified as code number 150/1-3, not patented, as the male, or pollen, parent. The new Anigozanthos was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Tuggerah, New South Wales, Australia.

Asexual reproduction of the new Anigozanthos by in vitro propagation of micro-plants in Tuggerah, New South Wales, Australia since October, 2001, has shown that the unique features of this new Anigozanthos are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Rambubona has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Rambubona’. These characteristics in combination distinguish ‘Rambubona’ as a new and distinct cultivar of Anigozanthos:

-   -   1. Compact and upright plant habit.     -   2. Freely and early flowering habit.     -   3. Freely branched flowering stems.     -   4. Large bright yellow-colored flowers.

Plants of the cultivar Rambubona can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Tuggerah, New South Wales, Australia, plants of the new Anigozanthos and the female parent selection differed in the following characteristics:

-   -   1. Plants of the new Anigozanthos had shorter leaves than plants         of the female parent selection.     -   2. Plants of the new Anigozanthos had longer flowers than plants         of the female parent selection.     -   3. Flowers of plants of the new Anigozanthos had yellow-colored         ovaries whereas flowers of plants of the female parent selection         had red-colored ovaries.

Plants of the cultivar Rambubona can be compared to plants of the male parent selection. In side-by-side comparisons conducted by the Inventor in Tuggerah, New South Wales, Australia, plants of the new Anigozanthos and the male parent selection differed in the following characteristics:

-   -   1. Plants of the new Anigozanthos had longer and more branched         flowering stems than plants of the male parent selection.     -   2. Plants of the new Anigozanthos had shorter flowers than         plants of the male parent selection.     -   3. Plants of the new Anigozanthos had shorter flowering stems         than plants of the male parent selection.

Plants of the new Anigozanthos can be compared to plants of the cultivar Bush Nugget, not patented. In side-by-side comparisons conducted in Tuggerah, New South Wales, Australia, plants of the new Anigozanthos differed from plants of the cultivar Bush Nugget in the following characteristics:

-   -   1. Plants of the new Anigozanthos were more freely flowering         than plants of the cultivar Bush Nugget.     -   2. Plants of the new Anigozanthos had shorter flowers than         plants of the cultivar Bush Nugget.

Plants of the cultivar Rambubona can also be compared to plants of the cultivar Bush Gold, not patented. In side-by-side comparisons conducted by the Inventor in Tuggerah, New South Wales, Australia, plants of the new Anigozanthos and the cultivar Bush Gold differed primarily in flowering habit as plants of the new Anigozanthos were more freely flowering than plants of the cultivar Bush Gold.
